BAD=86
BAD + ABC= 180
(8x+22) + (12x-2) =180
x=8
BAD = (8 x 8 + 22)
8 x 8=64
64 + 22 = 86
Step-by-step explanation:
I'm not sure what the ordered pairs due to you not providing them, but I can tell you the best way to see if they are solutions.
The best way to do so is by substituting the x and y values into the equation.
For example, if you had the ordered pair (5,2), then you would put the x coordinate in place of x and the y coordinate in the place of y.
Like so:
2 = -2(5)+6
The way you know if its a solution is if they equal the same thing.
Solution example:
2 = 2
Non-solution example:
5 ≠ 3

Answer:
5x - 2y = -2
Step-by-step explanation:
When subtracting one equation from the other, we are essentially just subtracting the left side of the second equation from the left side of the first equation and doing the same thing with the two right sides.
Here, we are subtracting (-7x + 3y) from (-2x + y):
(-2x + y) - (-7x + 3y)
Let's get rid of these parentheses. Remember that when we have a subtraction sign before a parentheses, we need to distribute a -1 to each term within those parentheses:
(-2x + y) - (-7x + 3y) = -2x + y + 7x - 3y = -2x + 7x + y - 3y = 5x - 2y
Now on the right side, we're subtracting 2 from 0:
0 - 2 = -2
Put it all together:
5x - 2y = -2
Hope this helps!
